摘要：
A manufacturing method of a metal strip coil for blades includes performing, on a steel band after a finishing cold rolling, a slit process that divides the steel band into a plurality of metal strips via joint operation of circular upper and lower blade cutters, and winding the metal strip into a coil shape after the slit process. In the slit process, a clearance of the upper and lower cutters is set within 5-25% of a metal strip thickness; an overlap amount of the upper and lower cutters is set within 5-80% of the metal strip thickness; and a clearance variation during the slit process is 30% or lower of the clearance. After the slit process, the metal strip is wound into a coil shape so that sag formed on an edge of the metal strip is positioned toward an axis center of a reel winding up the metal strip.
